God's condemnation of Edom

In chapter 35 God decides the controversy between Edom and Israel, and
condemns Mount Seir to perpetual desolation, because of the inveterate
hatred of that people to Israel; and instead of delivering up Israel
to Edom in the day that He chastises His people, it is Edom that shall
bear the punishment of this hatred, when the whole earth shall
rejoice. When God chastises His people, the world thinks to possess
everything; whereas that chastisement is but the precursor of the
world's judgment.
